Naso, A. Spelt, P. Date 2015-08-27 Abstract Bubble dynamics in turbulent flows has been extensively studied using the point-bubble approximation. But when the carrier flow varies on length scales smaller than the bubble size, this approximation is no longer appropriate and one needs to resolve all the scales present in the two-phase flow. 3D Direct Numerical Simulations of turbulent bubbly flows are carried out for bubbles ten times larger than the Kolmogorov length scale. The dynamics of large bubbles subjected to homogeneous isotropic turbulence and the turbulence modulation induced by their presence are investigated by mean of conditional statistics.
